Skid-mounted lubricating oil circulation device

Abstract

The invention relates to a lubricating oil device, in particular to a skid-mounted lubricating oil circulation device used for an oilfield sewage filter tank backwashing device. The skid-mounted lubricating oil circulation device comprises an oil tank and a circulation oil pump arranged on the oil tank. The circulation oil pump is connected with the oil tank through a circulation oil pump inlet pipeline. A circulation oil pump outlet pipeline is connected with an oil supply main pipeline and a pressure relief pipeline through a tee joint. The terminal of the oil supply main pipeline is connected with an electromagnetic valve set. All electromagnetic valve branches in the electromagnetic valve set are connected with all lubricated stirrer speed reducer oil spray nozzles through lubricating oil spray pipelines. The pressure relief pipeline is connected with a lubricating oil return pipeline. An outlet safety valve and pressure transmitter is installed on the pressure relief pipeline. One end of the lubricating oil return pipeline is connected with the oil bottom of a stirrer speed reducer case, and the other end of the lubricating oil return pipeline is connected with the oil tank. By means of the skid-mounted lubricating oil circulation device, the device failure rate can be decreased, the maintenance cost can be saved, automatic monitoring can be achieved, the patrolling efficiency can be improved, potential safety hazards can be eliminated, and stable operation of the device can be ensured.

Description

technical field [0001] The invention relates to a lubricating oil device, in particular to a skid-mounted lubricating oil circulation device used for backwashing equipment of an oil field sewage filter tank. Background technique [0002] With the continuous development of oilfields, the comprehensive water content of oil well production fluids has risen rapidly, and the sewage treatment capacity of gathering and transportation stations has increased. Considering various factors such as environmental protection and water injection, most of the oilfields currently treat sewage through first-level walnut shell filtration, second-level fiber ball filtration and third-level emery metal membrane filtration technologies to meet domestic sewage discharge standards, while filtration The quality of system backwashing has a great influence on the later water quality.

Problems solved by technology

[0003] In the existing filtration system, in actual production, the agitator often has the problem of jamming due to lubrication failure. The reasons are: (1) the agitator is installed on the top of the sewage filter tank, and there is a height difference (about 7 meters) from the ground, and The backwashing work is often carried out at night, and it is difficult and risky for employees to carry out frequent tank inspections through climbing ladders; (2) The lubricating oil pump and the stirring motor start at the same time, and there is not enough time to provide top-down lubrication to the gearbox in advance Oil, if the lubrication pipeline leaks or the oil pump fails, due to the lack of effective remote monitoring, the internal components of the filter tank reducer will not be lubricated in place, easy to wear and jam, resulting in the reducer and motor are prone to failure, resulting in serious wear and tear of the components, resulting in failure The use not only affects the normal operation of production, but also increases the maintenance of equipment and increases production costs.

[0004] CN201620358181.X discloses a lubricating oil circulation device, although it can realize the one-stop service of automatic lubrication and automatic collection of waste oil, shorten working hours, improve work efficiency, and realize unattended, but its remote control mode is wireless control, which is easy It causes static electricity, and there is a big safety hazard. It is not suitable for the safety requirements of Class A fireproof and explosion-proof oil and gas stations, and it is not suitable for the operation status of the oilfield sewage treatment system.
